Web2 days ago · An important protocol in quantum networks and cryptography, quantum state sharing works like this (in simple terms): a secret quantum state is divided into n shares and given to n players. The secret state can only be reconstructed if k (where k > n /2) players cooperate, while the remaining n - k players cannot access the information.
